Frequently Asked Questions
- What does "KB" mean in file size?
- KB stands for kilobyte (1,024 bytes). Online government portals and application forms specify maximum KB limits (like 20 KB or 50 KB) to optimize file uploads.
- Is image quality reduced during compression?
- For lossy formats like JPEG and WebP, compression intelligently balances visual clarity and byte size. For PNG, compression is lossless.
- Why might a target file size not always be achievable?
- Very high resolution images or high detail photos cannot always reach extremely small targets like 20 KB without excessive dimension reduction. The tool will provide the best available result and notify you if the target cannot be reached.
- Is my original image modified or overwritten?
- No. Your original photo remains untouched in local memory. You can switch target sizes or compress another photo without re-uploading.
- Which file formats are supported for compression?
- We support JPEG (.jpg, .jpeg), PNG (.png), and WebP (.webp) image formats.
